The 92FS is the same gun that I fell in love with as a teenager, and was the first firearm I ever bought. it's all been downhill since then! now I have 3 Berettas! 92FS, and it's military twin the M9, and a 96G Elite II, which is a factory "tricked out" piece. it has a Brigadier slide which is thicker and heavier than the normal slide, as well as a removable front sight (I actually added night sights to it because of this!), It also comes from the factory with the 92/96 "D" hammer spring which is lighter than the FS springs but still reliable with any ammo, it has the taller mag release button, skeletonized hammer, checkered front/rear straps, and a match grade barrel muzzle. I bought it for production pistol competition, and love it so much it's my CCW piece.
Glad you like it! One of my students had a Nano and found out he didn't like it so he traded for one like yours and loves it. He shoots it well too! By all means, shoot it often and try others as well. They are all fun, some more fun than others!
